Design Considerations for Crystallization and Purification of Vinylene Carbonate(VC)
Vinylene carbonate(VC)is an important additive for improving the cycle life and safety of lithium-ion batteries,and its market demand is growing rapidly.Crystallization and purification is an indispensable step in the production pro-cess of vinylene carbonate.In the industry,tubular crystallizers are common-ly used to purify vinylene carbonate,which requires a large investment in equipment and leads to unstable products.In this paper,a plate crystallizer is adopted,which has a low investment in equipment and can improve the puri-ty of the product.It has been verified in a certain project,and the product with a mass concentration of 99.998%has been obtained.From the perspec-tive of design,this paper introduces the design considerations for the plate crystallization and purification process of vinylene carbonate.
